1PC Spiral Flute Reamer 5.79-7.13 Diameter DIY Carbide Cutter Steel Tolerance Tool

Blade Nano Coating: The blade is coated with a nano-layer, which allows for direct rough to finish machining of materials heat-treated below 60°, reducing the number of tool changes and enhancing machine efficiency, thereby saving manufacturing time
NACO Coating: High Hardness
Steel Parts Buster: Widely Applicable
Applicable Materials: Gray cast iron, die steel, alloy steel, tool steel, spring steel, quenched and tempered steel.
Large Core Diameter Design: To achieve efficient machining: Upgrade the cutting edge/groove/core diameter ratio, fatigue resistance, and chip flow smoothness. Excellent resistance to resistance and vibration, reducing tool breakage
Carbide Material: Good toughness and high hardness. Hard tungsten steel alloy features high compatibility, high hardness, and high strength, ensuring smooth and fast cutting, making it a specialized milling cutter material for high-speed cutting applications
Toughness / High Hardness: Suitable for Blind Hole Machining
Gou grooves are CNC machined, smooth chip removal resistance is small
Helical Groove Design: Large capacity chip discharge groove discharges smoothly High efficiency and high precision
Chamfer Design: The handle has a chamfered design, making it easier to clamp
